Object-Oriented Programming in Kotlin is no longer accepting new enrollments. We've matched the highest-rated active courses in this subject:

Kotlin is an object-oriented language in the same style as Java, but also offers features found in newer languages like C# and TypeScript. This course will teach you to write a Kotlin application and make use of all the language.

Kotlin is an object-oriented language, and if you know a language like Java or C#, then you will know about classes, interfaces, and inheritance. However, Kotlin is expressive and extensible in ways that those older languages are not. In this course, Object-Oriented Programming in Kotlin, you’ll learn to write applications in Kotlin using the object-oriented features of the language. First, you'll explore how to define a class in Kotlin, and then add methods and properties. Then, you'll see how properties work, method overloading, visibility, and initializing objects at creation time. Next, you'll look at primary and secondary constructors, using the init method, and modeling data by using abstract classes, interfaces, and inheritance, including how interfaces can help you test your code. Finally, you'll dive into other class types such as sealed classes and data classes and how these make it easier to understand the meaning in our code. When you’re finished with this course, you’ll have the skills and knowledge of Kotlin needed to develop Kotlin applications.

Reviews summary

Mastering kotlin's object-oriented features

According to learners, this course is an excellent resource for developers transitioning to Kotlin from languages like Java or C#. Students consistently praise the instructor's clear explanations and the practical examples, making complex object-oriented concepts accessible. Key features like data classes, sealed classes, and constructors are particularly well-covered. While the course provides a strong foundational understanding, some advanced learners desired more depth or real-world application examples, especially for generics or testing, and it is not recommended for those entirely new to OOP.

Offers hands-on, practical examples for core concepts.

"I particularly loved the practical examples which made the concepts easy to grasp."

"The lectures are clear, and the code examples are helpful."

"Really clarified Kotlin's approach to OOP... Practicality is a strong suit here."

Perfect for developers transitioning from Java/C#.

"This course is absolutely fantastic for anyone coming from Java or C# who wants to understand Kotlin's object-oriented features."

"As a Java developer transitioning to Kotlin, this course was exactly what I needed. It bridged the gap perfectly."

"Fantastic course for transitioning Java/C# developers. The instructor beautifully articulates Kotlin's unique OOP constructs."

Instructor provides highly clear and concise explanations.

"The instructor explains complex topics like sealed classes and data classes with incredible clarity."

"The pace was perfect, and the instructor's delivery was engaging. Very practical and well-structured."

"The instructor's teaching style is clear and concise, making complex ideas easy to digest."

Could benefit from more advanced topics and real-world scenarios.

"I was hoping for more depth, especially for advanced patterns or design principles using Kotlin OOP. It feels more like a syntax tour."

"I felt some parts, especially around generics, could have had more advanced examples or practical use cases."

"My only minor feedback is that some explanations felt a bit rushed towards the end, particularly the 'Generics' module."

Requires prior understanding of object-oriented principles.

"Honestly, I found this course a bit disappointing. It assumes too much prior knowledge of OOP, which wasn't clear from the description."

"If you're a complete beginner to OOP, this is not for you. I struggled to follow without constant external research."

"It's clear this course is designed for someone already familiar with general OOP principles but new to Kotlin's specific syntax and paradigms."
